I’ve got Linux – So I’m safe, right?

You could still be vulnerable no matter what operating system you’re running.

There have been numerous high profile cases involving weaknesses in many flavours of Linux.
The ICS/SCADA KillDisk malware has resurfaced, now as a Linux variant, according to security firm eset.

And companies like Canonical (https://www.ubuntu.com/usn) maintain series of patches for Linux Kernel vulnerabilities, so there’s no excuse for not keeping up-to-date.
